CNC Milling Machines are advanced tools used in manufacturing to create precise parts and components. They operate by removing material from a solid block, using rotating cutting tools controlled by a computer program. This allows for high accuracy and repeatability in producing complex shapes. These machines can work with various materials, including metals, plastics, and wood. CNC stands for Computer Numerical Control, which means the machine follows specific instructions from a computer to perform tasks automatically. This technology has revolutionized industries by increasing efficiency and reducing human error in the production process.
